7 Claims. (Cl. 4-229) This invention relates to toilet seats. One of the objects of this invention is to provide, in a toilet seat, a reservoir opening to a vaporizing chamber, whereby a quantity of disinfectant or deodorant,

` either liquid or in the form of crystals, may be contained in the reservoir and released in small quantities into the vaporizing chamber, from which the vapors are dissipated into the room.

Another object is to provide one or more valves between the reservoir and vaporizing chamber having adjustment means whereby the rate of discharge of liquid disinfectant from the reservoir into the vaporizing chamber may be regulated.

Another object is to provide one or more filler openings to the reservoir, each closed by a resilient buffer.

The invention consists therefore in a hollow seat having a reservoir for containing a quantity of disinfectant or deodorant, or both, and a vaporizing chamber opening thereto through one or more valve controlled ports, and desirably, but not necessarily, containing absorbent material for absorbing liquid entering the vaporizing chamber and permitting the vapors therefrom to escape through perforations in a wall of the vaporizing chamber.

It further consists in a toilet seat provided with a vaporizing chamber having a removable perforated cover.

It further consists in a toilet seat having regulatable valve between the reservoir and Vaporizing chamber whereby the rate of discharge of the liquid from the reservoir to the vaporizing 5 chamber is governed.

It further consists in the several novel features of construction, arrangement and combination of parts hereinafter fully set forth and claimed.

The invention is clearly illustrated in the accompanying drawing, in which- Fig. 1 is a front elevation of a hollow seat, partly broken out, and fragment of a bowl, showing the seat raised;

Fig. 2 is a central, vertical section taken on the line 2-2 of Fig. 1;

Fig. 3 is a detail, fragmental, vertical crosssection, taken on the line 3 3 of Fig. 1; and

Fig. 4 is a detail, fragmental, vertical crosssection, taken on the line 4-4 of Fig. l.

Referring to said drawing, which is illustrative of one embodiment of the present invention, the reference character 5 designates a bowl of conventional form, and 6 a seat hinged thereto by a hinge 4connection l, as is customary. 55 The end of the seat, designated by the reference character 8, I shall call the top end" for convenience, and the end designated by the reference character 9, I shall call the bottom end. The upper side of the seat is designated by the reference character I0 and the lower side thereof by 5 the character II. l

The seat is formed of upper and lower sheets of metal I2, I3, III, stamped up with suitable dies to give them the conventional shape. The upper lower side is flat, as is customary.

The upper and lower metal pieces I2, I3 are soldered or seamed together at their edges to make tight joints. The seat is in the form of a hollow annular body, and the top end thereof 15 is separated from the lower end by transversely disposed partitions I5 which are soldered or otherwise fastened to the upper and lower sheets of metal I2, I3, so as to form a reservoir I6 at thel top end and a vaporizing chamber 22, at the 20 bottom end.

In the lower wall I3 at the top end of the seat is one or more filler openings II, each closed by rubber or other'resilient buffer I8, each buffer having a threaded stud I9 secured therein and 25 adapted to be screwed into a nut 20 which is soldered or otherwise fastened to the inner face of the wall I3. The reservoir is filled with a disinfectant or deodorant, or both, either of liquid or crystal form. The reservoir may be filled by un- 3 screwing one oi the buffers and pouring the dis'- infectant through the filler opening. Y

One or 'more .ports 2I are provided in the partitions I5 for permitting the contents of the reservoir to slowly escape into the vaporizing chamber 22. 'I'he ports 2| may be formed in nuts 23, soldered or otherwise secured to the upper sides of the partitions I5.. When a liquid disinfectant is used, valves 23 are provided, the bodies 24 of which are screwed into the nuts 23. The body of each ,valve is hollow and is formed at its upper end with a tapered Valve seat 25 upon which may seat a tapered valve head 26 which is formed upon one end of a valve stem 21 which extends down through the hollow of a body and out through its lower endand is threaded upon its lower end, and has an adjustment nut 28 threaded thereon; that bears against a washer 29 which, in turn, bears against the lower end of the valve body. A coiled compression spring 30, surrounding the valve stem, and bearing at one end upon the lower end of the cavity in the valve body and at the upper end against a pin 3|, fastened in the valve stem, serves to yieldably hold the valve head oil its seat. The nut 28 limits the size of 55 the clearance space between the valve head and its seat. By screwing up the nut 28, the valve head may be brought into very close proximity to the valve seat so that only a drop of the liquid may pass through the valve at a time. If desired, the nut may be unscrewed further, thereby increasing the size of the opening between the valve head and its seat to permit a. more rapid discharge of the liquid. The valve body is provided with a number of perforations 32 in its side wail for the escape of the liquid into the vaporizing chamber.

When a disinfectant or deodorant of crystal form is employed the entire valve may be removed, thereby permitting the crystals to drop through the port 2|.

The bottom side of the vaporizing chamber 22 is open, and is closed by a removable cover here-Y tofore designated by the reference character I4.

Desirably the cover I4 is secured in place by a friction joint 33, which extends around its entire margin. Any form of joint, for instance a slip joint, may be used for removably securing the cover I4 in place. The cover I4 of the reservoir is provided with a plurality of perforations 34 through which the vapors may escape from the vaporizing chamber to the outer atmosphere and, as a preference, absorbent material, such as sponges 35, or the like, may be contained in the vaporizing chamber to absorb the liquids and permit of the slow vaporization thereof.

In operation, the disinfectant or deodorant is introduced through either of the filler openings I1, into the reservoir I6 and the buffer screwed back into place. When liquid disinfectant or deodorant is used, it escapes very slowly through the clearance between the valve head and valve seat of the valve and enters the vaporizing chamber, where it is absorbed by the sponges or other absorbent material, and as the disinfectant or deodorant vaporizes, it escapes through the perforations in the cover.

More or less variation of the exact details of construction is possible without departing from the spirit of this invention. I desire, therefore, not to limit myself to the exact form of the construction shown and following claims, to point out all of the invention disclosed herein.

I claim as new, Patent:
